Any opinion so how the boat will perform? The boat is primarily a dinghy, and sees duty as a fishing/crabbing platform.

If it has power trim/tilt I would expect the top speed to be a little over 25 mph. A 25hp 13' whaler trimmed out will do high 20's. I remember growing up as kid as local guy had a 20hp merc on a 13'. If he had the boat fully loaded with people it would not plane off. Dave

The pro's - it will run a long time on a six gallon tank. The con's - Tops out around 23-25mph. The kids have pulled a kneeboard with it - but you would never be able to pull a waterskier,wakeboard or tube of any size. My kids are old enough for more HP now but we have stuck with the 20 for the time being. Of note - ours has power tilt but not trim - Having power trim would be nice.
